DATA INTEGRATION AND ANALYSIS SYSTEM

In the prior art, no method is disclosed for easily and in a short time extracting highly effective improvement measures and policies for all moving bodies or a specified moving body, and performing feedback to a moving body for which the improvement measures are necessary. A system for integration and analysis of data of a moving body in which detection data that was detected by sensors mounted in a controlled device of the moving body is gathered and a performance improvement index for the moving body is extracted from the detection data, wherein the system is characterized in that: correlation analysis is performed using an explanatory index generated from the operation status of the controlled devices, based on the performance index information for the moving body and the operation status of the controlled devices, using the performance index information for the moving body as a desired index; a data analysis central device gathers the analysis results for each moving body; and clustering analysis is performed, whereby an effective explanatory index for performance index improvement for each moving body is extracted, and the effective explanatory index is applied only to the moving body.
